CBS President Glenn Geller told Variety that they are “in negotiations, but it is definitely business as usual. We are guardedly optimistic that we will make a deal”.

When asked if the show would carry on without any of the three ‘main’ characters, Geller replied that “we want to get them all back. That’s the goal”.

Their contracts, which were signed back in 2014 for $1million per episode, are set to expire at the end of season 10.

Although, even more excitingly, Warner Bros TV and CBS have already started developing a Big Bang Theory prequel series which will be based on Sheldon’s childhood and teenage years in his deeply religious Texan upbringing.
